New Tar Sands Impact on Climate, Air Quality Found

New Tar Sands Impact on Climate, Air Quality Found

In one of the first studies of its kind, scientists have found that tar sands production in Canada is one of North America’s largest sources of secondary organic aerosols — air pollutants that affect the climate, cloud formation and public health. The study, published Wednesday in the journal Nature, showed that the production of tar sands and … Read More

U.S. Leads Globe in Oil Production for Third Year

U.S. Leads Globe in Oil Production for Third Year

The U.S. led the world last year in producing both oil and gas, federal government estimates published Monday show, even as the country committed to cutting greenhouse gas emissions. … Read More

Global Warming Will Hit Poorer Countries Hardest

Global Warming Will Hit Poorer Countries Hardest

New evidence that poorer countries will suffer the worst effects of climate change has shown that the number of hot days in tropical developing countries is likely to increase markedly as global warming takes hold. It has long been expected that poor people would bear the brunt of climate change, largely because so many more of the world’s poorest … Read More

Power Plant Emissions Fall to Lowest Level in Decades

Power Plant Emissions Fall to Lowest Level in Decades

Carbon dioxide emissions from electric power plants have fallen to their lowest level in decades, and that trend could help states meet their emissions goals under the Obama administration’s Clean Power Plan if it survives court challenges, according to new U.S. Energy Information Administration data and a New York University analysis. Carbon … Read More

Young Forests Can Store ‘Enormous’ Amounts of Carbon

Young Forests Can Store ‘Enormous’ Amounts of Carbon

Woodland areas that regrow after forest fires, logging operations or other disturbances can sequester huge amounts of carbon dioxide and they play an unexpectedly valuable role in mitigating climate change, according to a study by 60 scientists from across the globe. The research, published Friday in the journal Science Advances, is the first to … Read More

EPA Moves to Regulate Oil and Gas Methane Emissions

EPA Moves to Regulate Oil and Gas Methane Emissions

The Obama administration announced new rules on Thursday aimed at cutting methane emissions from new oil and gas wells and fracking operations. The rules also will require energy companies to provide pollution information to the Environmental Protection Agency so it can regulate methane emissions from existing oil and gas wells. Methane warms the … Read More

Global 2040 Forecast Sees Only Slight Fall in Fossil Fuels

Global 2040 Forecast Sees Only Slight Fall in Fossil Fuels

Despite the urgency to cut greenhouse gas emissions as climate change bears down on the globe, fossil fuel use is not likely to change much in the coming decades. Though renewable energy will grow quickly though 2040, gasoline and diesel will still move most of the world’s vehicles, and coal will still be the largest single source of carbon … Read More

Could Baby Steps Be the Best Global Climate Strategy?

Could Baby Steps Be the Best Global Climate Strategy?

Could baby steps be the best way to make international progress on slashing greenhouse gas emissions instead of trying to strike a bold and grand bargain among world powers? A paper published Monday in the journal Nature Climate Change concludes that the answer to that questions is: Yes. So far, international cooperation on climate change has come… Read More
